Abstract
AbstractThe influence of electron emission on the properties of the space charge sheath between plasma and wall is investigated theoretically using models of the stationary sheath. Especially, the following effects have been considered:Essential parameters of the sheath (e.g. potential drop, power flux density), of the wall surface (temperature, field strength, emission yield, Joule heat generation) and of the adjacent plasma layer (emission‐caused change of the electron temperature) have been calculated under self‐consistent conditions.From the obtained results several ways are discusséd indicating the development towards sheath instability and ending in the generation of plasma‐induced arc spots.
